Description

A hanging belt conveyor for coal mine transportation Technical Field

[0001] This invention relates to the field of coal conveying technology, specifically to a hanging belt conveyor for coal mine conveying. Background Technology

[0002] The coal mine hanging belt conveyor is suspended from the top of the roadway by steel ropes or brackets, without occupying ground space. It is suitable for narrow underground roadways and roadway deformation conditions. It is mainly used for connecting tunnel faces and long-distance material transportation, and is a key piece of equipment for efficient coal mine transportation.

[0003] In order to quickly obtain quality data before coal enters subsequent stages, such as washing, sales, and furnace feeding, and to intervene in production or adjust processes in a timely manner, for example, if sampling finds "excessive sulfur content," the batch of coal can be diverted to the "desulfurization line" in a timely manner to avoid direct entry into the power plant, it is necessary to sample and test the coal on the operating conveyor belt. The conventional sampling method is to manually sample the coal on the conveyor belt at regular intervals with a shovel. This method increases the workload of the staff, is inefficient, and the staff's proximity to the operating conveyor belt for sampling poses certain safety hazards.

[0004] To address the aforementioned problems, existing technologies offer several solutions. For example, patent application number CN202321591114.9 provides a sampling device for a coal conveyor belt, comprising a bottom support plate with a two-stage adjustable telescopic rod on the bottom support plate. A battery housing is located at the top of the two-stage adjustable telescopic rod. Auxiliary support rods are located on both sides of the battery housing, and a rotating rod is located at the top of the two auxiliary support rods. A turbine is mounted on the rotating rod, and a sampling tube is mounted on the rotating rod. A servo motor is mounted on the battery housing, and a worm gear is mounted on the output shaft of the servo motor. The worm gear and the turbine on the rotating rod engage with each other. An auxiliary frame is also provided on the battery housing. The auxiliary frame is equipped with a feeding hopper, which is located below the rear of the sampling tube. The controller controls the servo motor to rotate forward, and the sampling bucket can sample the coal on the conveyor belt. This facilitates the sampling function and allows for timed sampling of coal on the conveyor belt, saving manpower. However, this design uses a shovel-like sampling method. Since coal of various sizes is scattered on the belt, it cannot be guaranteed that the shoveled coal contains all the coal particles of all sizes on the belt. Furthermore, the chemical composition and physical properties of different particle sizes of coal vary significantly. If the collected sample does not contain coal of all sizes, it will affect the accuracy of subsequent testing. Summary of the Invention

[0005] The purpose of this invention is to provide a hanging belt conveyor for coal mine transportation, in order to solve the problem that the shovel sampling method during automatic coal sampling cannot guarantee that the shoveled coal contains coal particles of all sizes on the belt, thus affecting the accuracy of subsequent detection.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] A hanging belt conveyor for coal mine conveying includes a belt, with supports fixedly connected to both sides of the belt. A drive device and a detection device are fixedly connected to the supports. A housing is connected to the drive device. The housing has an installation chamber and a collection chamber. A motor, which is a dual-shaft motor, is fixedly connected inside the installation chamber. Opening and closing plates are slidably connected to both sides of the housing. A rotating shaft is fixedly connected to the output end of the motor on both sides. A bevel gear is fixedly connected to each rotating shaft on both sides. Rotary gears are provided on both sides of the installation chamber. Shaft 2 is rotatably connected to the outer casing of shaft 2. A bevel gear 2 is fixedly connected to shaft 2. The bevel gears 1 on both sides of shaft 1 mesh with the bevel gears 2 on both sides of the mounting chamber. A spur gear 1 is fixedly connected to shaft 2. A rack 1 is fixedly connected to the opening and closing plates on both sides of the outer casing. The rack 1 on the opening and closing plates on both sides mesh with the spur gears 1 on both sides of the mounting chamber. The collecting chamber is equipped with a screening assembly with a collecting hopper. The screening assembly is used to screen the coal between the opening and closing plates on both sides by size and collect it through the collecting hopper.

[0008] As is easily understood, conventional sampling by shoveling coal cannot guarantee that the shoveled coal contains all particle sizes from the conveyor belt, as various sizes of coal are scattered along the belt, thus affecting the detection accuracy. This design addresses this by incorporating a screening component inside the casing. When it is necessary to detect coal on the conveyor belt, the drive assembly moves the casing towards the belt, inserting the lower half of the casing into the coal on the belt. At this point, the drive assembly stops, and motor two starts, driving the worm gears on both sides to rotate. As the belt moves, some of the coal on the belt passes through the space between the opening and closing plates on both sides of the casing and enters the collection chamber. The coal enters the collection chamber and then into the collection hopper. During the sampling process, the motor starts and controls the opening and closing plate to gradually open, increasing the number of coal particles of different sizes entering the collection chamber. At this time, the screening component screens the coal, ensuring that the collection hopper collects only coal of each progressively increasing size at a time, without collecting too much of the same size. Therefore, this design allows the collection hopper to collect coal particles of all sizes from the conveyor belt as the opening and closing plate gradually opens and the screening component screens the coal. This enables the detection component to detect coal of various sizes, ensuring detection accuracy.

[0009] Preferably, the screening assembly includes a bevel gear three, the collecting hopper is disposed inside the collecting chamber and slidably connected to the outer shell, the bevel gear three is fixedly connected to a rotating shaft one, the rotating shaft three is rotatably connected to the outer shell, the two ends of the rotating shaft three are respectively located in the installation chamber and the collecting chamber, the end of the rotating shaft three located in the installation chamber is fixedly connected to a bevel gear four, the bevel gear three meshes with the bevel gear four, the end of the rotating shaft three located in the collecting chamber is fixedly connected to a bevel gear five, a screw is disposed inside the collecting chamber and rotatably connected to the outer shell, a bevel gear six is ​​fixedly connected to the screw, the bevel gear five meshes with the bevel gear six, the collecting hopper is threadedly connected to the screw, screening plates are disposed on both sides of the collecting chamber, a discharge port is disposed between the two screening plates, and the width of the discharge port gradually increases from the side closer to the opening and closing plate.

[0010] As is easily understood, when coal enters the collection chamber through the opening, it falls between the guide ramps on both sides of the screening plates. The coal then moves along the discharge port on these ramps. Since the width of the discharge port gradually increases from the side closest to the opening plate, the width of the discharge port at the bottom of the coal gradually increases. When the width of the discharge port exceeds the width of the coal, the coal falls from the discharge port and enters the collection hopper. Furthermore, each time motor one starts, the rotation of the shafts at both ends of motor one drives the rotation of bevel gear three, which in turn drives bevel gear four. Bevel gear four, through shaft three, drives bevel gear five, which in turn drives bevel gear six. Bevel gear six then drives the screw, causing the collection hopper to move along the screw... The machine moves towards a wider discharge port. When the opening and closing plate slides a certain distance, the motor stops. At this point, the opening and closing plate and the collecting hopper stop moving, and the opening width between the two opening and closing plates increases. The collecting hopper also moves to the bottom of the wider discharge port. Since larger coal cannot enter the collecting chamber, and smaller coal will fall back into the conveyor belt from the discharge port before moving to the collecting hopper, each time the motor starts, the collecting hopper will only collect one size of coal. This avoids the collecting hopper from being filled with small coal prematurely due to continuous collection, which would prevent it from collecting larger coal and thus reduce the detection accuracy. Therefore, this design improves the detection accuracy of the equipment.

[0011] Preferably, the opening and closing plates on both sides of the outer shell are arc-shaped, and the inner side of the opening and closing plates fits into the outer shell, and the rack is provided with an arc consistent with the opening and closing plates.

[0012] As is easily understood, during the sampling process, the motor controls the opening and closing plates to gradually open. At this time, the opening and closing plates on both sides will extend to both sides of the outer shell, which will block the coal flowing on both sides of the outer shell. This can easily cause the coal to accumulate and fall from both sides, resulting in waste. This design sets the opening and closing plates on both sides of the outer shell to be arc-shaped. When the coal moves to the surface of the opening and closing plates, the coal will slide along the surface to both sides of the outer shell. Furthermore, when the opening and closing plates open again, they no longer move laterally, but can slide open along the arc trajectory of the opening and closing plates. Therefore, this design avoids the opening and closing plates blocking the coal on both sides of the outer shell during the gradual opening process, thereby preventing the coal from accumulating and falling from both sides, thus avoiding waste.

[0013] Preferably, a guide slope is provided on one side of the screening plate, a worm gear is rotatably connected to the outer shell, a second motor is fixedly connected to the outer shell, the output end of the second motor is fixedly connected to the worm gear, and the two worm gears are parallel to the two sides of the discharge port respectively.

[0014] As is easily understood, when coal enters and falls between the guide slopes on both sides of the screening plates, it slides along the guide slopes by its own weight and the push of subsequent coal. However, since the guide slopes cannot transport coal like a belt, the increased friction between the coal and the guide slopes can easily prevent the coal from sliding, leading to blockage and preventing the collection hopper from collecting coal. This design addresses this by connecting a worm gear to the guide slopes. The worm gear is controlled by a motor. When coal enters the collection chamber through the opening between the opening and closing plates, it falls between the guide slopes on both sides of the screening plates. At this time, the irregular edges of the coal will contact the worm gear. When the worm gear rotates, it will drive the coal to move along the discharge port. Therefore, this design uses a worm gear drive to push the coal along the discharge port, avoiding the problem of increased friction between the coal and the guide slopes causing the coal to be unable to slide and resulting in blockage, thus improving the conveying capacity of the screening components.

[0015] Preferably, the outer shell is provided with a sliding rod, the sliding rod is located in the collection chamber, and a pressing plate is hinged to one end of the sliding rod in the collection chamber. A torsion spring is provided at the hinge point between the pressing plate and the sliding rod. The pressing plate is located directly above the discharge port, and the torsion spring pushes the pressing plate to rotate toward the discharge port.

[0016] As is easily understood, the outer casing is constantly impacted by the coal on the conveyor belt, causing it to vibrate continuously. When the worm gear rotates and transports the coal, the coal is easily affected by this vibration, causing it to bounce on the worm gear. This prevents the worm gear from making sufficient contact with the coal, thus affecting its conveying efficiency and reducing the sampling efficiency of the collection hopper. Furthermore, the bouncing can cause the coal to detach from the guide slope, preventing the collection hopper from collecting coal of the appropriate size. Therefore, this design incorporates a sliding rod on the outer casing. As large coal pieces move along the discharge port, a pressing plate at the top of the collection chamber applies pressure to them via a torsion spring, ensuring they are more firmly against the worm gear. This prevents the coal from detaching from the guide slope due to vibration and also increases the friction between the coal and the worm gear, thereby increasing the worm gear's conveying efficiency and improving the collection speed of the collection hopper.

[0017] Preferably, a spur gear two is fixedly connected to one end of the rotating shaft three located in the mounting cavity. A rack two is provided inside the mounting cavity and is slidably connected to the outer shell. The spur gear two meshes with the rack two. The sliding rod is slidably connected to the outer shell. One end of the sliding rod extends into the mounting cavity. A spring is provided between the sliding rod and the inner wall of the outer shell. An adjusting rod is fixedly connected to one end of the sliding rod located in the mounting cavity. An inclined plate is fixedly connected to one side of the rack two. The sliding rod contacts the surface of the inclined plate.

[0018] As is easily understood, as the opening and closing plates gradually open and the collecting hopper moves, larger pieces of coal can begin to enter the collecting chamber. However, due to the inconvenient position of the pressing plate, when larger pieces of coal enter, their height is closer to the hinge between the pressing plate and the sliding joint. The pressure exerted on the coal by the pressing plate increases with the size of the coal. This easily leads to the worm gear pushing the coal forward, while the pressing plate exerts a backward pushing force on the coal. This easily causes large pieces of coal to roll on the worm gear. This not only reduces the conveying efficiency of the worm gear, but also causes the coal to break due to continuous rolling and collision, thus leading to coal... If the coal falls prematurely from the discharge port and cannot accurately land in the collection hopper, this design addresses this issue by fixing a spur gear two at one end of the installation chamber. Whenever the motor starts, the rotation of the rotating shaft three drives the spur gear two to rotate, which in turn moves the rack two. The inclined plate on one side of the rack two also moves, pressing the adjusting rod on the sliding rod to raise the sliding rod. The sliding rod then drives the pressing plate to rise. As the size of the coal entering gradually increases, the pressing plate will gradually rise, ensuring that the pressure on the pressing plate remains consistent and does not increase when coal of different sizes enters the collection chamber. This prevents the coal from rolling due to the thrust of the pressing plate and improves the reliability of the equipment.

[0019] Preferably, multiple hinge plates are provided on both sides of the material discharge port, and the hinge plates on both sides are respectively hinged to the screening plates on both sides. A torsion spring is provided at the hinge point between the hinge plate and the screening plate. The screening plate is provided with the same number of inductive switches as the hinge plates. The inductive switches are in contact with the hinge plates and are electrically connected to the motor.

[0020] As is easily understood, this design uses multiple hinged plates on both sides of the discharge port. Whenever coal enters the collection hopper through the discharge port, the coal pushes the hinged plates to rotate. At this time, the hinged plates contact the induction switch, which then controls the motor to start. The opening and closing plates continue to open a certain distance, and the collection hopper moves a certain distance before the motor stops again. When the collection hopper collects coal falling from the discharge port again, the hinged plates are pushed again, which controls the motor to start again. This process repeats until the collection hopper moves to the end and collects the largest size of coal. This design, where the coal falls and contacts the hinged plates, allows the collection hopper to detect whether coal of the corresponding size has been collected more promptly, thus activating the motor to control the movement of the opening and closing plates and the collection hopper immediately. Therefore, this design improves the collection speed of the collection hopper and increases the sampling efficiency of the equipment.

[0021] Preferably, the screening plate has a discharge slope on the other side of the guide slope, and discharge ports are opened on both sides and the bottom of the outer shell.

[0022] As easily understood, this design works by ensuring that coal of the appropriate size, which fits perfectly between the two opening plates, automatically aligns with the guide ramps on both sides as the opening plates gradually open. However, some smaller pieces of coal, lacking the positioning of the opening plates, will fall directly onto the screening plate. If not cleaned in time, the coal inside the collection chamber will accumulate and cause blockage. This design addresses this by creating discharge ramps on the screening plate and discharge ports on both sides and the bottom of the outer casing. When coal falls onto the screening plate, it will flow along the discharge ramps and through the discharge ports back onto the conveyor belt. Therefore, this design prevents the coal from gradually accumulating in the collection chamber and causing blockage, which would affect the sampling of the collection hopper. Thus, this design improves the reliability of the equipment's sampling.

[0023] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0024] 1. This invention incorporates a screening component inside the outer casing. During sampling, the motor starts and controls the opening and closing plate to gradually open, increasing the number of coal particles of varying sizes entering the collection chamber. The screening component then separates the coal particles, ensuring that the collection hopper collects only coal of each progressively increasing size at a time, avoiding excessive collection of the same size. Therefore, this design allows the collection hopper to collect coal particles of all sizes from the conveyor belt as the opening and closing plate gradually opens and the screening component works, enabling the detection component to detect coal of various sizes and ensuring detection accuracy.

[0025] 2. By setting the opening and closing plates on both sides of the outer shell to be arc-shaped, when the coal moves to the upper surface of the opening and closing plates, the coal will slide along the surface to both sides of the outer shell. Furthermore, when the opening and closing plates are opened, they no longer move laterally, but can slide open along the arc trajectory of the opening and closing plates. Therefore, this design avoids the opening and closing plates blocking the coal on both sides of the outer shell during the gradual opening process, thereby avoiding the accumulation of coal falling from both sides and causing waste.

[0026] 3. This invention features a worm gear rotatably connected to the outer casing. The worm gear is controlled to rotate by a motor. When coal enters the collection chamber through the opening between the opening and closing plates, it falls between the guide slopes on both sides of the screening plates. At this time, the irregular edges of the coal will contact the worm gear. When the worm gear rotates, it will drive the coal to move along the discharge port. Therefore, this design uses a worm gear drive to push the coal along the discharge port, avoiding the problem of increased friction between the coal and the guide slope causing the coal to be unable to slide and resulting in blockage. This improves the conveying capacity of the screening component. Attached Figure Description

[0032] This invention provides a hanging belt conveyor for coal mine transportation, the technical solution of which is as follows:

[0033] Please refer to Figures 1 to 4. A hanging belt conveyor for coal mine conveying includes a belt 1, with supports 2 fixedly connected to both sides of the belt 1. A drive device 3 and a detection device 4 are fixedly connected to the supports 2. A housing 5 is connected to the drive device 3. The housing 5 has an installation chamber 6 and a collection chamber 7. A motor 8, a dual-shaft motor, is fixedly connected inside the installation chamber 6. Opening and closing plates 9 are slidably connected to both sides of the two housings 5. A rotating shaft 10 is fixedly connected to the output end of both sides of the motor 8. A bevel gear 11 is fixedly connected to both rotating shafts 10. A second rotating shaft 12 is provided on both sides inside the installation chamber 6. The second rotating shaft 12 is rotatably connected to the outer casing 5. A second bevel gear 13 is fixedly connected to the second rotating shaft 12. The first bevel gears 11 on both sides of the first rotating shaft 10 mesh with the second bevel gears 13 on both sides of the mounting chamber 6. A first spur gear 14 is fixedly connected to the second rotating shaft 12. A rack 15 is fixedly connected to the opening and closing plates 9 on both sides of the outer casing 5. The rack 15 on the opening and closing plates 9 on both sides mesh with the first spur gears 14 on both sides of the mounting chamber 6. The collecting chamber 7 is equipped with a screening assembly with a collecting hopper 16. The screening assembly is used to screen the coal between the opening and closing plates 9 on both sides by size and collect it through the collecting hopper 16.

[0034] Further, referring to Figures 1 to 4, the screening assembly includes a bevel gear 17, a collection hopper 16 disposed inside the collection chamber 7 and slidably connected to the outer casing 5, a bevel gear 17 fixedly connected to a rotating shaft 10, a rotating shaft 18 rotatably connected to the outer casing 5, with its two ends located in the installation chamber 6 and the collection chamber 7 respectively, a bevel gear 19 fixedly connected to the end of the rotating shaft 18 located in the installation chamber 6, and bevel gear 17 meshing with bevel gear 19, and a bevel gear 20 fixedly connected to the end of the rotating shaft 18 located in the collection chamber 7, a screw 21 disposed inside the collection chamber 7 and rotatably connected to the outer casing 5, and a bevel gear 22 fixedly connected to the screw 21. Bevel gear 5 20 meshes with bevel gear 6 22. The collecting hopper 16 is threadedly connected to the screw 21. Screening plates 23 are provided on both sides of the collecting chamber 7. A discharge port 24 is provided between the two screening plates 23. The width of the discharge port 24 gradually increases from the side closer to the opening and closing plate 9. The opening and closing plates 9 on both sides of the outer shell 5 are arc-shaped, and the inner side of the opening and closing plates 9 fits against the outer shell 5. The rack 15 is provided with the same arc as the opening and closing plates 9. A guide slope 26 is provided on one side of the screening plate 23. A worm gear 27 is rotatably connected to the outer shell 5. A motor 28 is fixedly connected to the outer shell 5. The output end of the motor 28 is fixedly connected to the worm gear 27. The two worm gears 27 are parallel to the two sides of the discharge port 24 respectively.

[0035] Please refer to Figures 1 to 4. A sliding rod 29 is provided on the outer casing 5, located within the collection chamber 7. A pressing plate 30 is hinged to one end of the sliding rod 29 in the collection chamber 7. A torsion spring is provided at the hinge point between the pressing plate 30 and the sliding rod 29. The pressing plate 30 is located directly above the discharge port 24. The torsion spring pushes the pressing plate 30 to rotate towards the discharge port 24. A spur gear 31 is fixedly connected to one end of the rotating shaft 18 located within the installation chamber 6. A rack 32 is provided inside the installation chamber 6 and is slidably connected to the outer casing 5. The spur gear 31 meshes with the rack 32. The sliding rod 29 is slidably connected to the outer casing 5, with one end extending into the installation chamber 6. A spring 25 is installed between the inner walls of the housing 5. An adjusting rod 33 is fixedly connected to one end of the sliding rod 29 located in the installation chamber 6. An inclined plate 34 is fixedly connected to one side of the rack 2 32. The sliding rod 29 is in contact with the surface of the inclined plate 34. Multiple hinge plates 35 are provided on both sides of the discharge port 24. The two hinge plates 35 are respectively hinged to the two screening plates 23. A torsion spring is provided at the hinge point between the hinge plate 35 and the screening plate 23. The screening plate 23 is provided with the same number of induction switches as the hinge plates 35. The induction switches are in contact with the hinge plates 35 and are electrically connected to the motor 8. A discharge inclined surface 36 is opened on the other side of the guide inclined surface 26 of the screening plate 23. Discharge ports 37 are opened on both sides and the bottom of the outer casing 5.

[0036] Please refer to Figures 1 to 4. When it is necessary to detect the coal on belt 1, the drive assembly controls the housing 5 to move towards belt 1. The lower half of the housing 5 will insert into the coal on belt 1. At this time, the drive assembly stops, and motor 28 starts and drives the worm gears 27 on both sides to rotate. As belt 1 moves, the coal on belt 1 will contact the opening and closing plates 9 on both sides of the housing 5 and slide along the surface of the opening and closing plates 9 to both sides. At this time, the opening width between the opening and closing plates 9 is at its minimum value. When coal smaller than the opening width between the opening and closing plates 9 passes by, the coal will enter the collection chamber 7 through the opening. At this time, the coal will fall between the guide slopes 26 on the screening plates 23 on both sides. At this time, the irregular edges of the coal will contact the worm gears 27, and the worm gears 27 will rotate. The worm gear 27 moves the coal along the discharge port 24. Since the width of the discharge port 24 gradually increases from the side closest to the opening plate 9, the width of the discharge port 24 at the bottom of the coal gradually increases as the worm gear 27 moves the coal. When the width of the discharge port 24 is greater than the width of the coal, the coal falls from the discharge port 24 and enters the collection hopper 16. During the fall, the coal contacts the hinge plate 35 on the discharge port 24. The hinge plate 35 rotates under pressure and contacts the inductive switch. At this time, the inductive switch controls the motor 8 to start. The rotating shafts 10 at both ends of the motor 8 rotate and drive the bevel gears 11 on both sides to rotate. The bevel gears 11 then drive the bevel gears 13 to rotate. The bevel gears 13 drive the spur gears 14 to rotate through the rotating shaft 12. The first 14 drives the rack first 15 to move, and the opening and closing plates 9 on both sides of the outer shell 5 slide along the outer shell 5. When the rotating shaft first 10 rotates, it also drives the bevel gear third 17 to rotate. The bevel gear third 17 drives the bevel gear fourth 19 to rotate. The bevel gear fourth 19 drives the bevel gear fifth 20 to rotate through the rotating shaft third 18. The bevel gear fifth 20 then drives the bevel gear sixth 22 to rotate. The bevel gear sixth 22 drives the screw 21 to rotate. At this time, the collecting hopper 16 moves along the screw 21 toward the wider part of the discharge port 24. When the opening and closing plates 9 slide a certain distance, the motor first 8 stops. At this time, the opening and closing plates 9 and the collecting hopper 16 stop moving. The opening width between the opening and closing plates 9 on both sides increases, and the collecting hopper 16 also moves to the bottom of the wider part of the discharge port 24 because the opening width between the opening and closing plates 9 on both sides increases. As the collection chamber 7 expands, larger pieces of coal will enter. These larger pieces, along with the smaller ones, will enter the chamber together. Due to the increased width, some of the smaller coal will not fall between the guide slopes 26 on the two screen plates 23, but will instead fall onto the discharge slopes 36 on both sides and return to the conveyor belt 1 through the discharge port 37. The smaller pieces of coal that enter between the guide slopes 26 on the two screen plates 23 along with the larger coal will also move along with the larger pieces via the worm gear 27. At this point, the width of the discharge ports 24 at the bottom of the larger and smaller coal sections gradually increases. The smaller pieces of coal will fall first, but because the collection hopper 16 has moved to a wider position in the discharge port 24, they will fall back onto the conveyor belt 1 through the discharge port 37.Larger pieces of coal move above the collecting hopper 16 and fall into it. As they fall, they contact the hinge plate 35, triggering the sensor switch again. This causes the opening plate 9 and the hopper to move further, allowing even larger pieces of coal to enter the collecting chamber 7. This process repeats until all sizes of coal are collected. As the larger pieces of coal move along the discharge port 24, the pressing plate 30 at the top of the collecting chamber 7 applies pressure via a torsion spring, ensuring the coal adheres more tightly to the worm gear 27. Furthermore, whenever the motor… Each time motor 8 starts, the rotation of shaft 18 drives spur gear 31 to rotate, which in turn moves rack 32. The inclined plate 34 on one side of rack 32 also moves, pressing the adjusting rod 33 on sliding rod 29, causing sliding rod 29 to rise. Sliding rod 29 then drives pressing plate 30 to rise, allowing larger amounts of coal to enter collection chamber 7 with each start of motor 8. Pressing plate 30 can accommodate all sizes of coal. After all coal of various sizes has been collected, the drive assembly controls the housing 5 to move to the detection assembly, which then detects the coal inside collection hopper 16.

For those skilled in the art, various changes, modifications, substitutions, and variations made to these embodiments without departing from the principles and ideas of the present invention should still fall within the protection scope of the present invention.
